Abstract
A kind of damping unit that can improve heavy rail machining accuracy, the air holes that the damping block connected by side cover plate, the front shroud be connected with side cover plate, the adjusting bolt be connected on front shroud, the back shroud be connected with side cover plate inwall, side cover plate rear end, back shroud are arranged forms, its damping block is connected with back shroud, and adjusting bolt is fixed together by connecting bolt and air holes.The utility model makes saw blade good stability in sawing process, gap adjustment between damping block and saw blade is directly regulated by adjusting bolt, the machining accuracy of heavy rail is improved, and it is easy to adjust, structure is simple, can not stuck phenomenon be produced, reduce the replacing number of times of saw blade, effectively enhance productivity.
Description
Technical field
The utility model relates to a kind of part of appliance auxiliary processing device, specifically belongs to a kind of damping unit that can improve heavy rail machining accuracy.
Background technology
The sideshake amplitude of heavy rail saw blade in Cutting indexes process is very large on the impact of processing heavy rail section gradient, iron mark hundred meters of high speed heavy rail section gradient requirement≤0.6mm, and section requires smooth.Damping unit is the equipment for controlling side-sway amplitude in saw blade sawing process, and technological requirement itself and saw blade surface distance are 0.1 ~ 0.2mm.Existing damping unit regulates feeding bolt by the advance of spring band dynamic damping block and retrogressing, thus reach the object adjusting itself and saw blade gap, due to the secondary transmittance process that its adjustment feeding is power, namely front shroud Compress Spring is passed through by adjusting bolt, promote damping block by spring again to move, thus the gap realized between damping block and saw blade, there is un-reasonable phenomenon due to structure in it, therefore in the process of centering rail, exist following not enough: often cause the section gradient of middle rail to exceed standard and section out-of-flatness, have a strong impact on saw blade lifetime; Spring structure adjustable stroke is limited, often will make up by increasing packing ring in using; Field working conditions is severe, because on-the-spot iron filings are more, in use easily produces stuck phenomenon, brings certain difficulty to adjustment; Saw blade can produce side-sway power in sawing process, and saw blade direction of feed can be made to occur to depart from a little when side-sway power is excessive, when side-sway power is greater than certain value, spring can lose the effect of stable saw blade direction of feed, causes machining accuracy poor, cannot meet the demands.
Utility model content
The purpose of this utility model is to overcome prior art above shortcomings, a kind of saw blade good stability in sawing process is provided, gap adjustment between damping block and saw blade is directly regulated by adjusting bolt, and it is easy to adjust, structure is simple, can not produce the damping unit that can improve heavy rail machining accuracy of stuck phenomenon.
Realize the technical measures of above-mentioned purpose:
A kind of damping unit that can improve heavy rail machining accuracy, the air holes that the damping block connected by side cover plate, the front shroud be connected with side cover plate, the adjusting bolt be connected on front shroud, the back shroud be connected with side cover plate inwall, side cover plate rear end, back shroud are arranged forms, it is: damping block is connected with back shroud, and adjusting bolt is fixed together by connecting bolt and air holes.
Feature of the present utility model: saw blade is good stability in sawing process, gap adjustment between damping block and saw blade is directly regulated by adjusting bolt, the machining accuracy of heavy rail is improved, and it is easy to adjust, structure is simple, can not stuck phenomenon be produced, reduce the replacing number of times of saw blade, effectively enhance productivity.
Accompanying drawing explanation
Fig. 1 is that center line of the present utility model analyses and observe structure schematic diagram;
In figure: 1-side cover plate, 2-front shroud, 3-adjusting bolt, 4-back shroud, 5-damping block, 6-air holes, 7-connecting bolt.
Detailed description of the invention
Be described further below in conjunction with accompanying drawing:
A kind of damping unit that can improve heavy rail machining accuracy, the air holes 6 that the damping block 5 connected by side cover plate 1, the front shroud 2 be connected with side cover plate 1, the adjusting bolt 3 be connected on front shroud 2, the back shroud 4 be connected with side cover plate 1 inwall, side cover plate 1 rear end, back shroud 4 are arranged forms, damping block 5 is linked together by bolt and back shroud 4, and adjusting bolt 3 is fixed together by connecting bolt 7 and air holes 6.
When needing the gap between damping adjusting block 5 and saw blade, screw the adjusting nut in adjusting bolt 3, screw rod can be made to pass through to drive connecting bolt 7, thus make back shroud 4 drive damping block 5 to carry out moving forward or retreating, until the gap adjustment between damping block 5 and saw blade puts in place.
This detailed description of the invention is only the best and exemplifies, the restricted enforcement not to technical solutions of the utility model.
